ycLEAiiiiiefA AND Pci-.isiiiivs MACHINE,

To nall fio/tom it may concern.'

Be it knownthat I, Lno H. ILL-mo, a

of Chicago, county of Cook, and State of Illinois, have invented certainnew anduseful Improvements in Cleaning and Polishing Machines, of whichthe following is declared to be a full,clear, and exact description. f

This invention 1 relates to cleaning and polishing ymachines Vof thatclass adapted for cleaning and polishingfknives, forks, spoons and thelike, and has particular reference to the `rotary brushes'thereof-whichperform the cleaning and ipolishii'ig operation. Brushes of rthis kindare usually of ring like formation, the bristles projecting laterallyfrom the ring; two brushes'are employed in each machine andthey are setwith the bristles of onebrush opposing and contacting `with those of theother brush. The brushesare revolved *rapidly and kthe seited betweenthem. y

When sharp knives are operated on by the brushes, it frequently happensythat the bristles are cut and often one or ythe other of the brushes isdestroyed or damaged to such an extent that a new brush must besubstituted therefor. The brushes are ysomewhat expensive and therepairs are costly, due to frequentreplacement of the brushes.

The principal' object of this `invention is to minimize the cost ofrepairs by providing sectional brushes, in the forni of segments whichmay be removed from and replaced by new ones when worn out or damaged.

Another object is tov compensate for the Wear on the edges of thebristles of any sec-` tion left in the machine when new brush sectionsare inserted to takey the placeof worn out or' damaged ones.

To such ends the invention consists in the several novel featureshereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawing furnished herewith,in which:

` Figure 1, is a view of a cleaning and polishing machine embodying onerform of the present invention, the View being partly in side elevationand partly in central vertical section; F ig. 2, is a view partly in endelevation and partly in vertical cross section, taken on the line 2-2 ofFig. l, showing one of the brush sections partly broken Specification ofLetters Patent.

,tric flanges 21, 22,

away and'Fig.` 3, is a perspective view of a e i ybrush section used inthe machine. citizen of the United States, anda resident Referring tosaid drawing, 10, designates a driveishaft mounted in bearing brackets1l, and carrying a pulley 12, arranged to be driven in any suitablemanner as, for instance, byA 'means of a belt running from any suitablesort of power. Mounted upon said shaft are two circular brush carryingheads 13, 13a, the" head 13, being fixedly secured to the 'shaft `bymeans of a collar 14:,"fast on lthe shaft and having pins 15,whichprojec't intoholes in theweb l6,.of the head. The other head 13a,is slidably mounted on the shaft 10, and" is spring pressedytoward thefixed head 13,by means of a coiled coin-` pression spring 17,interposedy between a collarlS," fast'on the shaft, and the web 19,

of the head, 13a. i

Theheads 13, 13e," are designedto carry brushes which operate on thearticles to be y' "cleaned, and inasmuch as both brushes, and articlekto be cleaned and polished is inthemeans for connecting them to theheads, are substantially similar, a description of one head and brushsections, carried thereby, will be suiiicient so far as thisspecification is concerned.

Each brush carrying head is formed with an annular groove 20, betweentwoconcen-L that frcrn the web 16, and said groove is adapted for thereception of the back of an annular brush 25. The brush comprises aplurality of segmental sections 24, 24a, the backs 25, of which seat inthe groove 20, and have screw threaded pins 26, secured therein, whichproject out through holes'27, inthe web of the brush carrying head. Saidpins are secured in the backs 25, in any suitable manner and they arehere shown as provided with nuts 28, that are let into recesses in thesectional brush backs, and when screwed up tight against the backs,rigidly fasten the screw threaded pinsto the back. Nuts 29, are threadedupon the outer ends of the screw threaded .pins 26, and bear against theouter face of the web 16, to se-V Patented Nov. 16, l1915...'Application filed August 21,1913." Sera110.`785,841. l l' projectlaterallyV ice natedv by the reference numeral'ia, is 'one Whosebristles are shorter than the bristles of those shovvn in? the othersections,such as would be the'case if they had been Worn down 'fromconsiderable usage, and the other Vthree Worn out sections hadibeenreplaced Washers may be of different thicknesses so as to properlybackup the-brush section. e having the short length bristles., and thereby.bringA the ends of the bristles, or rather the Workingrface of thesection, flush With the Workingface of thebristlesof the other sections.These Washers may surround the screw threaded pins 26, if so desired,and by tightening up` the-'nuts on thel pins'this VVbrushsection:may beproperly secured in place, With its Working racecontacting With theWorkingy face of theopposite brush section. A N v In use, the shaft andbrush heads and brushescarried thereby, are revolved, and if desired,cleaning and polishing powdersmay be applied to the brushes, vafterwhich the article to be cleaned is inserted between the contacting facesof the brushes and held there until the cleaningand polishing operationhasbeenperform'ed. y I Yrealize thatY various Valterations andvmodifications of this device are possibile without departingv from thespirit of this inf vention and I do not therefore desire to limit'myselfto the exact details of construction shown and'described.- l,

I claim as new and desire to secure byLetters Patent: Y

In, a cleaning and polishing machine, a

rotary, disk-like, brush-carrying head, 'and Yan'annularV brush having aback piece and bristles secured therein and projecting therefrom inlinessubstantially parallel with the axis of rotation of said head, oneof said members havingstuds iXedly secured thereto andprojectingtherefromin lines vparallel With said axis of Vrotation- V andv theV`other member having-holes for/the reeption of said st uds wherebyrotation of one; member with respect to theother is prevented.
